First milestone is reached: the first flashable firmware image is a fact.   Grin

Please give a reply in this thread if you're willing to test it. It's really experimental so here are the terms:

- I am not responsible for any damage to your miner, flash at your own risk
- You're not in panic when you see HW errors because of the low voltage Wink
- You do have a watt meter
- You're willing to test and give me feedback for improvement.
- You're not going to complain about the 1.5% mining fee.

what you will get:
- no more high speed fan's during startup
- no more low fan warnings (the fan speed is fully unlocked)
- a first version of the unlocked voltage.

If you do join this beta test, please test the following:
set the speed to 400Mhz on your bitmain firmware and measure the amount of watts needed.
flash the beta firmware and set fan speed to manual at 20%
set the speed to 400Mhz and try to get as low as you can on the voltage settings before you see hardware errors.

PM me then the following information:
- your batch
- the wattage at 400mhz on the bitmain firmware
- The voltage on the custom firmware so that you run at the same wattage as the bitmain firmware
- The lowest possible voltage setting for 400mhz on the custom firmware. (before getting HW errors)
- the wattage measured at the new voltage
- your fan RPM speed at 20% fan setting

ofcourse if you run in any other problems please PM me as well.  Wink


I want test too,I have the wattmeter.Thanks
